1. •Understanding how a materials microstructure
changes as a result of fatigue and high
temperatures is important to designing with new
ultra strong materials. [1]
•This study is on the implementation and
modification of a lamp furnace for in-situ materials
testing.
•Neutron beam is an ideal candidate for observation
of change in micro structure. [2]
• The Installation of lamp furnace on load frame
• Thermal analysis using finite element analysis
• High temperature test on sample specimen
• Redesign of insulation for reduced beam
interference.
• Positioning lamp furnace considerations:
 No interference with operation of test stand
 Effective heating of test specimen
• Thermal analysis
 CAD model of test set up using solidworks
 Thermal analysis of model using Ansys
• High temperature test
 Record and compare result with model
analysis
• Redesign of furnace insulation
 Reduced interference with neutron beam
 Easy of fabrication and installation

Benefits:
• Easier fabrication
• Easier installation
• Increased height for decreased beam interference
• Optimal installation position found
• Thermal analysis and high temperature test
was preformed
• Temperature fluctuations were with in an
acceptable range for in-situ testing
• Comparison showed >1% difference between
center measurements and >2% difference
between side measurements
• Redesign of insulation completed
•Easier fabrication and installation
•Reduced beam interference
• Profiling of furnace interference during neutron
beam test
• Submit beam line time proposal for high
temperature test
• Perform in-situ test
