Metal additive manufacturing (MAM), also known as metal 3D printing, is a rapidly growing
industry based on the fabrication of complex metal parts with improved functionalities …

In this study, the fabrication of hybrid metal-matrix-surface composites (HMMSC) through the
friction stir process (FSP) was investigated, where hexagonal boron nitride (HBN) was used …

In this paper, the grain refinement of a 5052 aluminum alloy was achieved using two
different fabrication approaches. In the first approach, the grains in the investigated alloy …

In the current work, wrought AA2024 alloy sheets were used as the base metal matrix and
reinforced with SiC, BN nanoparticles, and VC particles; hence, friction stir process FSP is …

Microstructure homogeneity, uniform elements distribution, and good mechanical properties
are the main research challenges after the continuous laser melting (CLM) process. Adding …

In order to achieve the goal of lightening the braking system of urban rail trains, SiCp/ZL101
and ZL101 plates were welded by friction stir lap welding (FSLW) to prepare a new type of …

Abstract Using the Al-Zn-Mg-Cu alloys for the laser melting processes is a challenge due to
the formation of hot cracks and pores in the fusion zone. This challenge can be solved by …

The formation mechanisms of intermetallic layers and the development of the interface
between solid brass and molten Al alloy were experimentally investigated using semi-infinite …

Abstract In this paper 0.8, 1.2, 1.6 and 2 wt.% of submicron-TiB 2 particulate reinforced Al
7075 metal matrix composites (MMCs) were fabricated following a modified liquid metallurgy …

Laser welding of AA7075 and Ti6Al4V, two very different aerospace alloys, was performed
with a copper (Cu) interlayer to avoid the brittle Ti–Al intermetallics. The joint was formed …
