TL;DR: In this article, a two-dimensional numerical model was developed to simulate the evolution of grain structure observed during the laser additive manufacturing process, where a cellular automata method was used to describe grain growth and the Goldak heat source model was adopted to calculate the heat input during laser melting.

TL;DR: In this paper, a three-dimensional numerical model is developed to evaluate fundamentals of grain structure evolution during metal additive manufacturing, and the results obtained show that specific solidification conditions in selective laser melting and grain selection associated with competitive nature of grain growth promote the development of coarse columnar grains with the most favorable growth direction misaligned with the build direction.

TL;DR: In this article, the authors focused on the numerical analysis of the temperature distribution in the vicinity of the melt pool during laser beam melting process depending on the local geometry of the part.

TL;DR: Aerospace carbon fiber-reinforced components are cured under high pressure (7 bar) and temperature in an autoclave as discussed by the authors, where the loading of an auto-closet usually changes from high pressure to high temperature.

TL;DR: In this paper, the authors described a method of tempering a steel platebody between the austenization and hot-working, which consists of fixing the steel plate body at a position, contacting a first contact plate (2) with a first surface portion (6), contacting a second contact plate with a second surface part (7), and forming the contact plates flatly or completely corresponding to the contour of the surface portions and arranging them parallel to each other in a running manner.
