Micro-Texture Analyses of a Cold-Work Tool Steel for Additive Manufacturing

Evolution of solidification texture during additive manufacturing.

Striking differences in the solidification textures of a nickel based alloy owing to changes in laser scanning pattern during additive manufacturing are examined based on theory and experimental data. Understanding and controlling texture are important because it affects mechanical and chemical properties. Solidification texture depends on the local heat flow directions and competitive grain gr...

Surface texture metrology for metal additive manufacturing: a review

A comprehensive analysis of literature pertaining to surface texture metrology for metal additive manufacturing has been performed. This review paper structures the results of this analysis into sections that address specific areas of interest: industrial domain, additive manufacturing processes and materials; types of surface investigated; surface measurement technology and surface texture cha...

Comparison of Maraging Steel Micro- and Nanostructure Produced Conventionally and by Laser Additive Manufacturing

Maraging steels are used to produce tools by Additive Manufacturing (AM) methods such as Laser Metal Deposition (LMD) and Selective Laser Melting (SLM). Although it is well established that dense parts can be produced by AM, the influence of the AM process on the microstructure-in particular the content of retained and reversed austenite as well as the nanostructure, especially the precipitate ...

The Effect of Deep Cryogenic Treatment on Microstructure, Hardness and Wear Behavior of INDRA 5 Cold Work Tool Steel

Manual for transference work scale; a micro-analytical tool for therapy process analyses

BACKGROUND The present paper is a manual for the Transference Work Scale (TWS). The inter-rater agreement on the 26 TWS items was good to excellent and previously published. TWS is a therapy process rating scale focusing on Transference Work (TW) (i.e. analysis of the patient-therapist relationship). TW is considered a core active ingredient in dynamic psychotherapy. Adequate process scales are...
