| Summary: | The aim of this study is to investigate experimentally the microstructural evolution of the joints using ledeburitic AISI D2
Tool Steel parts. The application of a new process of the semisolid joining of two parts of AISI D2 cold-work tool steel
is proposed using a partial remelting method. Samples were heated in an argon atmosphere up to 1300°C and held for
10 minutes. Metallographic analyses along the joint interface showed a smooth transition from one to the other and
neither oxides nor microcracking was observed. The current work successfully confi rmed that avoidance of a dendritic
microstructure in the semisolid joined zone and high bonding quality components can be achieved without the need for
force or complex equipment when compared to conventional welding processes. |
