I bought all the necessary items, carefully selecting each to fulfil my needs.
As I looked at the purchased items, a surge of excitent coursed through , causing a slight tremor in my hands. With eager anticipation, I placed the tallic object on the table, observing it with great satisfaction.
Although the items I acquired were quite ordinary in nature, consisting of everyday chemical utensils, chemicals, electronic scales, and cutting tools, their significance to my experint was imasurable.
Taking utmost precaution, I switched on the ventilation fan and closed the blinds, creating a controlled environnt for my undertaking. It was ti to comnce the ticulous verification process.
The first task was to determine this enigmatic tal's density. I began cutting into the tal with the cutting tool in my grasp.
After considerable ti and effort, it beca apparent that this tal possessed an extraordinary combination of characteristics. Despite its lightweight nature, it exhibited a hardness surpassing that of ordinary steel. I persevered, ultimately slicing off a small piece using an electric cutting tool.
The freshly cut surface glead with a distinct tallic lustre, reinforcing my conviction that this was indeed a remarkable tal, potentially of extraterrestrial origin.
The next step was to ascertain its weight. Carefully placing the cut tal piece on an electronic scale, I observed the needle settling at 27.35 grams.
Utilizing a asuring cylinder to determine its volu, I ticulously calculated the density using a calculator, arriving at a value of 2.6.
Comparing this density to known materials, such as iron (7.8), titanium alloy (approximately 4.5), and aluminium alloy (2.7), it beca evident that this grey-black tal boasted a density slightly higher than that of aluminium alloy. Truly fascinating!
The weightlessness of this tal, coupled with its resistance to deformation, exceeded even that of aluminium alloy. It possessed a remarkable hardness, surpassing that of ordinary steel.
Intrigued by its corrosion resistance, I decided to subject it to various acids, such as sulfuric acid and hydrochloric acid. Astonishingly, no reaction occurred.
Refusing to succumb to doubt, I prepared a glass of aqua regia and introduced the tal shavings from the previous cutting into the solution. Aqua regia, known for its formidable corrosive properties capable of dissolving gold, exhibited sluggish corrosion when in contact with these tal shavings.
Undeterred, I stirred the mixture with a glass rod, hoping to accelerate the reaction. However, the corrosion process remained sluggish. Accepting its sluggish nature, I allowed the response to progress at its own pace, carefully noting the ti required for a complete reaction.
Eager to unveil more secrets, I conducted a series of experints that yielded astonishing results. It beca apparent that this tal possessed an extraordinarily high lting point. Even after subjecting it to intense heat for an extended period, it did not exhibit signs of redness or alteration in colour. Instead, it maintained its black and grey hue.
To confirm the reliability of my fla, I swiftly tested it with an iron wire, which swiftly turned red and white under the searing heat. This ensured that the fla possessed a temperature in excess of 1200 degrees Celsius, approaching the lting point of iron wire at over 1500 degrees Celsius.
After conducting a comprehensive series of tests, I began to form a preliminary understanding of this enigmatic tal. Its characteristics included low density, high lting point, exceptional hardness, and remarkable corrosion resistance.
Overwheld by awe, I couldn't help but marvel at its origin, recognizing that it far surpassed the technological advancents of Earth's civilization.
However, certain specific properties, such as hardness, tensile strength, flexibility, and lting point, remained unverified due to the lack of specialized equipnt and institutions capable of conducting such analysis.I think you should take a look at
Contemplating the next course of action, I pondered whether sending the tal to a professional institution for thorough testing was prudent. Without delay, I made the decision to entrust the cut piece of tal, weighing a re 20 grams, to the utmost care. I ticulously wrapped it with multiple layers of plastic film before assigning Qiu Yang to deliver it.
The tal piece was destined for the most esteed professional institution in Yanguo, the Institute of Special tal Materials under the renowned Yanguo Academy of Sciences. The recipient of this precious cargo would be none other than Hu Jianguo, the esteed director of the institute. Revered as an authoritative expert in the realm of unique tal materials and a respected academician of the Yanguo Academy of Sciences, Hu Jianguo's expertise was indispensable for unravelling the mysteries of this extraordinary tal.
anwhile, Hu Jianguo was engrossed in a eting with a distinguished guest within the hallowed halls of the Institute of Special tal Materials. The visitor in question was none other than Liang Chengwen, a renowned authority in aero-engine technology in Yangshuo.
Liang and Hu shared a deep bond, having graduated from the sa university in the sa class. While their fields of expertise diverged, with one specializing in materials and the other in aero-engine design, their friendship endured. They understood the paramount importance of materials science in the realm of cutting-edge aero-engine developnt.
Yanguo, though possessing formidable aero-engine technology, remained a generation behind certain developed nations. While Yanguo boasted third-generation aero-engine capabilities, so advanced countries had already attained fourth and fifth-generation aero-engine technology.
Concerned for Liang's progress, Hu inquired, "Old friend, how is the developnt of Turbofan X progressing?"
Turbofan X represented a fourth-generation engine featuring a design thrust-to-weight ratio of 10:5 and vector nozzle technology. Its intended use was for the new dostically developed fifth-generation fighter, making it a project of imnse national significance.
With great expectations and ample support from the country, the developnt process of Turbofan X encountered nurous obstacles and setbacks, presenting a formidable challenge.
Liang Wencheng sighed softly, his face etched with a touch of bitterness as he replied, "There are still so unresolved issues, the most critical being the inability to increase the temperature ahead of the turbine and the limited lifespan of the turbine blades."
The temperature before the turbine in an aero-engine held significant importance. Advanced engines could withstand temperatures surpassing 1800 degrees Celsius in that region. With such extre heat, nurous tals would lt, let alone function effectively and generate substantial thrust.
This necessitated the use of particular tals known as superalloys. These alloys were not ordinary by any ans. They required powder tallurgy techniques to withstand higher temperatures and an array of cooling designs to ensure the longevity of turbine disks and blades in such demanding conditions.
Liang Wencheng harboured dreams of pushing the temperature limits of Turbofan X ahead of the turbine and enhancing the service life of the blades. However, the existing materials fell short of their aspirations.
"I've co to you, Jianguo, seeking your assistance," Liang pleaded with a sense of urgency. "We require a material that can rival the imported high-temperature alloys. Otherwise, our Turbofan X project will remain stagnant."
Hu Jianguo's expression grew serious as he contemplated the gravity of the situation. He responded slowly, "Quenching this thirst may not be an easy task. While we have initiated a project aid at localizing single crystal superalloys, it will still take at least five to eight years before we can achieve industrial-scale application."
The prospect of waiting for such a prolonged period left Liang Wencheng disheartened. The tiline was too extensive, and their project couldn't afford such a delay.
Importing single crystal superalloys from abroad wasn't a viable solution either. It was imnsely challenging, but the exorbitant prices and potential supply disruptions posed significant risks.
Liang Wencheng's mind sank as he contemplated the dilemma they faced.
Interrupting their conversation, a knock resounded on the office door. Hu Jianguo's assistant entered, holding a courier package in hand.
