Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Snow grain-size measurements in Antarctica [PDF]
AbstractGrain-size is an important but not well-known characteristic of snow at the surface of Antarctica. In the past, grain-size has been reported using various methods, the reliability, reproducibility and intercomparability of which is not warranted.

This paper takes the ultra-fine grain AZ80 magnesium alloy multi-directionally forged as the research object. We observe its heating behavior at 673 K with an optical microscope, analyze the grain size distribution, and the change of average grain size ...

Effect of grain size on the corrosion resistance of low carbon steel
Systematic works on the effect of grain size on the corrosion resistance of low carbon steel are scant. In the present work, a spectrum of grain sizes was obtained by simple heat treatment routes in a typical low-carbon steel.

Size Distribution of Grains Growing by Thermal Grain-Grain Collision [PDF]
The time variation in the size distribution of dqst grains is. investigated for the case where the grains are in thermal motion under the impact of ambient gas molecules and they are growing by sticking in grain-grain collisions. The growth of grains in this manner may be expected to occur in .highly dense interstellar .clouds (or protostars) and ...
