Conventional and two-step heating transient liquid phase bonding (TLP) experiments of martensitic precipitation hardeningstainless steel 17-4-PH were studied employing AMS 4777 braze filler at temperature of 1050 °C for different times (15 to90 min) to accomplish the ideal brazing condition. The effect of TLP methods and bonding conditions on the microstructureand shear bond strength was investigated. The critical bonding time for isothermal solidification in conventional and two-stepheating TLP was 60 min and 45 min, respectively. The microstructure of isothermal solidification zone consisted of Ni-richsolid solution phase. Eutectic constituents Cr-rich boride and Ni3Siwere formed in the joint centerline in the athermallysolidified zone. In the conventional method planar interface was formed, however in TLP bonding under temperature gradientnon-planar interface was formed, high angel grain boundaries merged at the end of isothermal solidification and homogenousbond was produced. Due to the decrease of athermally solidified zone the shear strength increased by increasing the holdingtime and when using the two-step heating process because of better metal to metal contact, the shear strength was higher. The optimum condition was a temperature gradient TLP in 60 min bonding time, which led to shear strength of 435 MPa.
