Work Description

The project's goal is to continue the study of a method of joining pieces of steel by isothermal diffusion (this is called TLPB). Our group is working on this line since 1999 and the first stage of this project is intended as an exhaustive study of the mechanical properties and welded specimens. These welds were made with carbon steel pipe as base material and amorphous FeB ribbons and FeBSi as filler. It will examine the role of boron and its influence on mechanical properties. With a view to their application in industry, arises as a secondary objective to increase the diameter of the welded samples, is to be achieved with solder pipes up to 110 mm in outer diameter. It also wants to change the filler sheets of pure metals (eg copper) that are compatible with the steel used.

With these amendments will be made unions analyzing the influence of process variables: temperature, pressure, process time, cooling rate, finish of mating surfaces, etc.. These welding techniques are characterized by light and electron microscopy, and they will test ended. We will study their mechanical properties. In a final stage, this method is applied to the junction of alloy (eg: 4340 AISI).
