Abstract
The influence of cold deformation on liquid metal embrittlement of a steel in a liquid zinc bath was studied. A typical construction steel was cold deformed with different degrees. The microstructure of the different material conditions were investigated as well as their mechanical properties at 450 °C in hot air. Tensile tests with different strain rates were made in a 450 °C hot zinc bath. For each specimen the reduction in area was determined and the fracture surfaces were studied. It can be shown that the strain rate has a large effect on liquid metal embrittlement. An increasing degree of deformation leads to a decrease on liquid metal embrittlement which is caused by the change of microstructure through deformation.
