Abstract
With the development of society, every year there are increasing demands in the automotive industry on cost savings, environmental safety, reduction of raw material consumption, performance improvement, material life cycle and recycling of components. In this review, emphasis is given on ferrous and non-ferrous alloys, which are used as components, where both groups can be treated by deep cryogenic treatment (DCT). DCT has shown to increase hardness, tensile strength and wear resistance, reduce density of defects in crystal structure, improve toughness and corrosion resistance. Though, some researchers also reported results that showed no change in material properties, or even deterioration of material properties, when subjected to DCT. This additionally points out to lack of consistency and reliability of the DCT process, which is needed for its successful incorporation in automotive applications. However, to prove with certainty the resulting outcome on the material properties and knowledge about the reasons for the variation of this effect on metallic materials, further approach and testing with different variables should be conducted in the future. This review provides a synopsis of different approaches of DCT on different materials for automotive applications in order to indicate effects on the material performance during DCT.
Highlights
With development of society and science, every year newly-developed metallic materials are presented for automotive applications as a response to an increasing demand on environment safety, reduction of material consumption, recycling of the material, improvement of material life cycle performance and, cost savings [1,2,3,4]
deep cryogenic treatment (DCT) can be found in literature named as sub-zero treatment (SZT) [42] or ultra-low found in literature named as sub-zero treatment (SZT) [42] or ultra-low temperature process (ULTP)
The possible explanation could be in the absence of carbon and the much different phase formation mechanisms found in non-ferrous alloys
Summary
With development of society and science, every year newly-developed metallic materials are presented for automotive applications as a response to an increasing demand on environment safety, reduction of material consumption, recycling of the material, improvement of material life cycle performance and, cost savings [1,2,3,4]. Market demands on driving comfort, safety and every year’s new designs of the vehicles, give rise to many additional parameters to be fulfilled by the selected material [5,6]. To cope with these increasing demands, different approaches on enhancement of properties of metallic materials are being developed nowadays. The most common technique of heat treatment for automotive applications applies processing temperature set higher than 0 ◦ C (>273 K). Metals 2020, 10, 434 later development of the technique various other properties such as strength, hardness and corrosion resistance have been reported to change and added to the designated properties to be manipulated during subzero treatment. One of the jewels of subzero treatments is the deep cryogenic treatment (DCT), which is the main topic of this review
