The joint of 40Cr steel and TiAl based alloy has been studied by means of a
high frequency induction diffusion welder. The experimental results show t
hat, the higher the temperature and pressure, the higher the strength of th
e joints. The optimum parameters are: T=1123 similar to 1323 K, t=10 simila
r to 30 min, P=5 similar to 20 MPa.
