RESEARCH PROJECT

DC4
FATIGUE AND FRACTURE MECHANICS OF COLD SPRAY ADDITIVELY MANUFACTURED METALS AND ALLOYS

Objective

  1. Selection of industrially relevant metals, compilation of knowledge database of their fatigue and fracture-mechanics properties
  2. Performing comprehensive high-cycle fatigue testing of the materials and relating to other mechanical properties
  3. Performing fracture-mechanics testing of the materials using sub-sized specimens

Expected Results

  1. Identification of materials for current or new application fields (mostly in aviation, aerospace, and automotive)
  2. Thorough fatigue and fracture-mechanics characterization of CSAM materials leading to understanding of the CS specific microstructures influence as opposed to metallurgic counterparts
  3. Constructing a complex durability and damage tolerance assessment approach (e.g., for airworthiness certification of CSAM parts)
