前言真空淬火工艺中,油淬是应用比较多的一种方法。但在高强度钢30CrMnSiNi2A制作的航空重要受力构件上,国内尚未见有应用先例。对30CrMnSiNi2A钢进行真空加热后油淬与目前通常应用的热处理油淬方法如:盐炉油淬、电炉油淬及涂料保护电炉油淬相比,组织和性能有什么不同?真空油淬在30CrMn-SiNi2A航空构件上应用存在什么问题?本文根据一系列试验结果,从组织、特别是某些性能的角度,对此问题进行了一些初步探讨。试验内容一、试验用钢采用102钢厂生产的φ18毫米30CrMnSiNi2A棒材,炉号为6414。成分:C 0.27％、Cr1.14％、Mn1.19％,Si1.07％、Ni1.68％、Cu<0.15％、S 0.004％、P 0.007％。
Foreword Vacuum quenching process, oil quenching is a more applied method. However, in the high-strength steel 30CrMnSiNi2A aviation important force components, there is no domestic precedent. The 30CrMnSiNi2A steel after vacuum heating oil quenching and the current commonly used heat treatment oil quenching methods such as: salt furnace oil quenching, electric furnace oil quenching and paint protection electric oil quenching compared to the organization and performance What is the difference? Vacuum oil quenched in 30CrMn- What problems exist in the application of SiNi2A aeronautical components? Based on a series of experimental results, this article makes some preliminary discussions on this issue from the perspective of organization, especially some properties. Test content First, the test steel produced by the 102 steel φ18 mm 30CrMnSiNi2A bar, furnace number 6414. Composition: C 0.27%, Cr 1.14%, Mn 1.19%, Si 1.07%, Ni 1.68%, Cu <0.15%, S 0.004%, P 0.007%.
