Material Properties at Low Temperature

TL;DR

This paper reviews how material properties such as electrical, thermal, mechanical, and magnetic behaviors change from ambient to cryogenic temperatures, providing essential data for cryogenic system design.

Contribution

It introduces mechanisms affecting material properties at low temperatures and supplies data sets for materials used in cryogenic engineering.

Findings

Material properties vary significantly at cryogenic temperatures.

Data sets for common cryogenic materials are provided.

Understanding these variations aids in designing reliable cryogenic systems.

Abstract

From ambient down to cryogenic temperatures, the behaviour of materials changes greatly. Mechanisms leading to variations in electrical, thermal, mechanical, and magnetic properties in pure metals, alloys, and insulators are briefly introduced from a general engineering standpoint. Data sets are provided for materials commonly used in cryogenic systems for design purposes.
