The results show a significant decrease in mechanical strength for samples that are built diagonally and a transformation of the microstructure after a HIP ( hot isostatic pressing ) treatment , resulting in a lower maximum strength , but higher ductility .
 machanical property: mechanical strength; concept or principle: samples; concept or principle: microstructure; manufacturing process: HIP; manufacturing process: hot isostatic pressing; machanical property: strength; machanical property: ductility
