Multi‐Scale Structural Effects of External Electrical Fields of Melt Tracks in Laser Powder Bed Fusion

open access: yesAdvanced Science, EarlyView.
Laser material processing is a promising technique for fabricating metal structures. Here, external electric field (EFs) assisted laser processing of metallic powders are investigated. EFs affect the melt tracks through changes in their stability and influence the grain structure in conjunction with laser intensity distribution methods. The EF‐assisted

Steepest Descent Method

2019
The steepest descent method is one of the oldest and well-known search techniques for minimizing multivariable unconstrained optimization problems. This method has played an important role in the development of advanced optimization algorithms. It is a first-order derivative iterative optimization algorithm whose convergence is linear for the case of ...

A new steepest descent method

AIP Conference Proceedings, 2014
The classical steepest descent (SD) method is known as one of the earliest and the best method to minimize a function. Even though the convergence rate is quite slow, but its simplicity has made it one of the easiest methods to be used and applied especially in the form of computer codes. In this paper, a new modification of SD method is proposed using
