Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

SIGMA-SAFE: A phase diagram approach to the sigma phase problem in ni base superalloys

Metallurgical and Materials Transactions A - Physical Metallurgy and Materials Science, 1978
A new procedure for evaluating the sigma phase precipitation tendency of superalloys has been developed. It is called SIGMA-SAFE. Phase diagrams are used to determine the degree of super saturation with respect to precipitation of the sigma phase as a function of temperature and alloy compositions.

The Sigma Phase

International Materials Reviews, 1966
AbstractThe sigma phase, which occurs in transition-metal alloy systems, is of interest in both the technological and the theoretical field of alloy formation. In the former, the sigma phase is important because of its occurrence, with generally deleterious effects, in stainless and other high-alloy steels, while in the latter case a knowledge of the ...

Sigma-phase in steel 1Kh20N14S2

Metal Science and Heat Treatment of Metals, 1961
1. Dispersion hardening of steel 1Kh20N14S2 at 650°C occurs in two stages. The first stage lasting up to 500 hrs is characterized by the precipitation of secondary carbides Me23C6 and their coalescence, principally along austenite grains. The second stage is connected withσ-phase formation. 2.

Sigma Phase in Tungsten-Rhenium Alloys. I

Materials and Manufacturing Processes, 1996
Abstract In developing tungsten alloys for service both above the recrystallization temperature and below room temperature the main task is to make an alloy, which in addition to having a low ductile to brittle transition temperature in the recrystallized condition can readily be manufactured into various configurations.
