中碳钢的高温力学行为
On Mechanical Behaviour at High Temperature for Carbon Steel
【摘要】 借助Gleeble1500热模拟试验机,测试了45钢自凝固点至600℃温温度范围内的强度和塑性变化规律,并就加热方式、应变速率、冷却速度等因素对凝固温度区、奥氏体区和γ→α相变区的强度和塑性的影响进行了研究,还对3个区形成裂纹的机理进行了初步探讨。
【Abstract】 The rules of stength and ductility for 45 steel under temperature range from solidus to 600℃ were measured by a thermal stress/strain simulator Gleeble 1500. The influence of thermal history, strain rate and cooling rate on strength and ductility at solidifying region, Austenitic region and γ→α region was studied. The mechanism of cracking in these three regions was investigated.
