HSLA钢连续控制轧制对其显微组织和机械性能影响的研究表明,这类钢的轧制变化经适当选择能显著地提高它的性能,显示出小尺寸原始奥氏体经轧制,随后在奥氏体的非再结晶区连续控轧导致细小的铁素体晶粒和细小的珠光体晶粒。这就使得HSLA钢 Studies of the effects of continuous controlled rolling of HSLA steels on their microstructure and mechanical properties have shown that the choice of rolling variation for such steels can significantly improve their performance, revealing the small size of the original austenite being rolled and subsequently Continuous controlled rolling in the austenite non-recrystallization zone results in fine ferrite grains and fine pearlite grains. This makes HSLA steel
