•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
