During the fifth forging experiment, Ji Yuan had basically refined a special steel with a yield strength of over 600 MPa. Even though this special steel was still inferior to the HY-100 developed by American laboratories years ago, it was already considered remarkable by these experts and scholars.
The reason for this mindset stemmed from the long-standing shortcomings in materials science, which had severely undermined their confidence. Ji Yuan couldn't help but twitch his lips; the data report these guys presented to the leaders of the National Security Department was quite rough, merely stating that research and development were progressing steadily. They probably felt embarrassed themselves, as they had nothing substantial to show.
If it weren't for the higher-ups urging them to quickly produce special steel for aircraft carriers, they wouldn't have directly sought help from their leaders. Ji Yuan was fully immersed in the experimental forging process. After more than ten adjustments to the material ratios, he finally grasped the pattern. He had a hunch that the special steel produced this time should meet the standards!
As the yield strength testing equipment operated, everyone was on edge. However, when the final value appeared on the yield strength instrument, everyone was left dumbfounded. The yield strength value had reached 802 MPa! At that moment, not only the experts but even the researchers assisting them couldn't help but curse at the readings on the instrument.
"Could it be that the instrument is broken?"
In just over five hours, Ji Yuan had managed to create a material with a yield strength suitable for aircraft carrier structural steel?
What have they been researching for so many years? Is it luck, or is their strength worlds apart from Ji Yuan's?! The steel with a Yield Strength of 802 MPa is appearing for the first time in the entire Special Steel Secret Research Institute. This data has basically caught up with America's most advanced HLSA-115 Special Steel.
Seeing that the Yield Strength finally met the standards for Aircraft Carrier structural steel, Ji Yuan secretly breathed a sigh of relief. Noticing their excitement was hard to contain, Ji Yuan quickly said, "In addition to the high Yield Strength requirement, Aircraft Carrier steel also has the most important Fire Resistance requirement!"
The Aircraft Carrier deck experiences extremely high speeds during aircraft takeoffs and landings, generating a lot of heat due to intense friction. If the Fire Resistance of the steel material does not meet the standards, even if the Yield Strength is high, it would still be useless.
Of course, using it to make a show and proclaiming that the Eastern power has made significant breakthroughs in Yield Strength would still impress quite a few people.
The experts were not concerned about that; they were already as excited as children. "Yes, yes, let's hurry and conduct the Fire Resistance tests!"
After years of fruitless research, suddenly seeing hope made them feel greatly comforted— even though this Special Steel was not forged by them, witnessing its birth from nothing still stirred their emotions!
The steel was placed under Fire Resistance testing, with blue flames at extremely high temperatures shooting directly at the steel. 2000 degrees Celsius is the minimum Fire Resistance requirement for deck steel.
The flames emitted when Carrier-Based Aircraft take off from the deck reach temperatures ranging from 2000 degrees Celsius to 3000 degrees Celsius.
2000 degrees Celsius is the minimum requirement and serves as a threshold. However, even so, the Special Steel Research Institute has not produced any qualified Special Steel. The highest experimental data for the steel they studied showed a Yield Strength of 632 MPa and Fire Resistance of around 1800 degrees Celsius, which falls far short of the standards for Aircraft Carrier structural steel.
Currently, this steel's Yield Strength meets the requirements for Aircraft Carrier steel; the key factors now are its Fire Resistance and other properties. If this steel can achieve Fire Resistance above 2000 degrees Celsius, it can be preliminarily confirmed that it indeed meets the requirements for Aircraft Carrier deck steel.
Under the high-temperature spray of 2000 degrees Celsius, that seemingly ordinary piece of steel showed no change in color. This means that 2000 degrees Celsius is still far from its melting point.
"Increase it to 2300 degrees Celsius!" Ji Yuan commanded in a low voice to the researchers beside him while wearing goggles and protective clothing.
"Understood." The researcher controlling the equipment raised the temperature to 2300 degrees Celsius.
The intense heat caused beads of sweat to form on everyone's bodies, making them feel somewhat uncomfortable. However, no one chose to step back in order to witness the limits of this steel's Fire Resistance.
At 2300 degrees Celsius, the steel still showed no significant reaction.
Ji Yuan simply instructed the researchers to raise the temperature to 3000 degrees Celsius.
In an instant, the entire laboratory felt like a furnace, so hot that it was difficult to breathe. Every breath taken felt 'scorching' as it filled the lungs.
At a temperature of 3000 degrees Celsius, the steel began to undergo slow changes. These changes were very subtle and could easily be overlooked if one was not paying attention.
The steel gradually exhibited slight color changes, but its overall condition remained almost unchanged. This meant that the extreme heat of 3000 degrees Celsius was still not enough to completely affect the steel!
Around Ji Yuan, the experts and researchers had already clenched their fists, excited to the point of wanting to shout. However, considering that the experiment was still ongoing, their good scientific discipline kept them in check. At the same time, they were eager to see the fire resistance limit of this piece of steel.
