Abstract

The goal of the present work is to evaluate mechanical properties and to analyse the microstructure of 316L stainless steel produced by Laser Powder Bed Fusion (L-PBF) follow by rolling with different thickness reduction under ambient and cryogenic conditions. The samples before rolling were heat treated. The static tensile test was realized at ambient and cryogenic (77K) conditions. The L-PBF powder metal production technology approved that is a key technology in the AM area, especially for metal powder materials. Mechanical properties tested at 298K and 77K shows that the application of various thermo-deformation rolling conditions increases of strength properties. Achieved mechanical properties are comparable to conventional bulk materials. The strength properties after the rolling under ambient and cryogenic conditions were significantly increased.

Highlights

  • Additive manufacturing (AM) is a technology that has wide possibilities for producing materials and products of common as well as extraordinary properties through powder metallurgy (PM)

  • PM products are exceptional due to their features and because their price is significantly lower than products produced by other technologies [1,2,3,4,5,6]

  • Laser Powder Bed Fusion (L-PBF) technology is important in PM

Summary

Introduction

Additive manufacturing (AM) is a technology that has wide possibilities for producing materials and products of common as well as extraordinary properties through powder metallurgy (PM). The biggest benefits are: possibility to produce components of very complicated shapes, use of extremely hard and solid materials, production of composite materials and last but not least, high material savings. AM technologies can achieve up to 90 – 95 % of material savings. With the help of progressive technologies, it is possible to recycle the used powder material and increase the percentage of its utilization up to 100 % [7,8,9,10,11,12]. Laser Powder Bed Fusion (L-PBF) technology is important in PM. With a laser beam melt the powder particles in a precisely defined field and liquid phase can be achieved in a very
