Strength Tests

The article provides an overview of studies on the influence of HIP on the density, roughness and mechanical properties of cast aluminum alloys. As a result of HIP, the density of the alloy, its ductility, and cyclic characteristics increase, and the scatter of mechanical properties determined during tensile and long-term strength tests decreases. The use of HIP increases the yield of good casting due to the reduction of rejects due to unacceptable porosity detected during х-ray inspection. Thus, the casting acquires a homogeneous, completely dense structure.
