摘要
选择390Q超细高强钢为研究对象,比较了390Q与16MnL钢的相关性能,详细研究了390Q超细高强度钢的显微组织与性能的变化规律和特性,指出390Q超细高强度钢焊接时有焊缝热影响区的强度自补特性,证明390Q超细高强度钢是较合适的重型车冲焊桥壳的制造材料。
Choose the hyperfine high strength steel of the 390Q as research object,relatively to study the related function of 390Q steel and the 16MnL steel.Research the 390Q microstructure the hyperfine high strength steel of the variety regulation and characteristic that the organization and function learn the temperature impact behind,as the strength that the welding sews the heat influence area when the super and thin high strength that points out the 390Q steel just welds from repair the characteristic ,Prove the 390Q steel super and thin high strength steel is the manufacturing material of the blunt welding bridge hull of a car.
