Scope and Objectives
Demonstrate additive manufacturing of land base power turbine parts in through additive manufacturing in a consortium approach
Deliverables
Process optimisation of industrial selective laser melting process to specific materials and part geometries Process optimisation of direct metal deposition processes to the same material and part geometries Comparison of the processes Development of required property data bases Demonstration of consistency Development of process and quality control and test and evaluation standards Cost benefit analysis
Scientific Output
Design of experiments for process optimization that Control of solidification in tempered martensite materials in the two processes to minimize solidification defects. Design of laser path and power/beam size parameters for solidification and surface finish control Development of new heat treatment procedures for additively manufactured parts in the proposed materials. Achievement of residual stress control and mechanical properties including tensile, creep and fatigue that compare with conventionally manufactured parts
Results and outcome till date
MOU between partner industries and IISc signed Powder procurement and characterization Parameter optimization trials completed Heat Treatment effects evaluated
Societal benefit and impact anticipated
Such a demonstration would pave the way for the development of industry specific standards for additive manufacturing
Next steps
Optimize heat treatment and mechanical behaviour on trial blocks Demonstrate prototype parts
