Critical role of subgrain orientation on the stability of mechanical properties of selective laser melting manufactured alloys

In this work, it was found that the orientation of columnar grains is determined by the growth direction of subgrains within them. The difference in deformation between orientation grains and other orientation grains is an important factor that affects the stability of mechanical properties of SLM m...
