直到最近为止 ,人们认为淬火是造成零件畸变的一个主要工艺过程 ,特别是淬火的具体操作过程。而今 ,众所周知淬火过程只不过是释放了零件在整个加工过程的一系列操作中积累起来的畸变潜能。然而 ,迄今为止 ,还没有一个以系统的方式来研究和精确测定整个过程以及每一个加工步骤对零件的几何尺寸、成分偏析、显微组织和残余应力分布的影响。从 2 0 0 1年开始 ,由DeutscheForschungsgemeinschaft(德国研究基金 )在不来梅大学成立了“畸变工程”(SFB 5 70 )合作研究中心 ,本文介绍了这一长期工程的基本研究方法和构架
Until recently, it was considered quenching is a major part of the distortion caused by the process, especially the specific operation of quenching process. Today, it is well-known that the quenching process simply releases the distortion potential accumulated by a part over a series of operations throughout the process. However, to date, there has not yet been a systematic way to study and accurately determine the effect of the entire process and the geometry of each part, composition segregation, microstructure and residual stress distribution for each process step. Beginning in 2001, the “Distortion Project” (SFB 5 70) Collaborative Research Center was established by the Deutsche Forschungsgemeinschaft (German Research Foundation) at the University of Bremen. This paper presents the basic research methodology and architecture of this long-term project
