Thermal electron beam(EB) joining of steel matrix composites (A07)

子项目A7的研究重点是采用高能电子束（EB）对铸态TRIP/TIPs钢与颗粒增强复合材料或镍基合金进行热连接。此外，还对冷轧TRIP/TTRIP复合材料的局部短时电子束退火进行了研究。特别地，研究了用于调制化学或热处理循环的工艺参数的相互作用以及对显微组织和机械性能的影响。在空间分辨二维温度测量的基础上，对能量转移点/场的穿透进行了模拟。TP T1

The research emphasis of subproject A7 is the thermal joining of as-cast TRIP/TWIP steels with particle reinforced composites or Ni-base alloys using a high-energy electron beam (EB). Furthermore, the local short-time EB annealing of cold-rolled TRIP/TWIP material is investigated. In particular, the mutual interaction of the technological parameters for the modulation of the chemical or thermal treatment cycle and the impact on the microstructure and the mechanical properties are studied. Simulations of the penetration of the energy transfer spot/field are accompanying the work on the basis of space-resolved 2D temperature measurements.TP T1
