Synthesis & characterization of natural soil based inorganic polymer foam for thermal insulations
Syed Farrukh Alam Zaidi,Ehsan Ul Haq,Khushnuda Nur,N. Ejaz,M. Anis-ur-Rehman,Muhammad Zubair,Muhammad Naveed +6 more
TL;DR: In this article, natural soil based inorganic polymer foams have been successfully produced using low cost and abundantly available soil as an aluminosilicate precursor, which can potentially be used as building thermal insulations.

Failure due to structural degradation in turbine blades
TL;DR: In this paper, the Udimet 500 turbine blades of an engine were found chipped off during a test run and the cause of failure was found to be intergranular crack(s) which started during exposure to high temperature.
20
Effect of high temperature exposure on the microstructure of Udimet-500 super alloy
TL;DR: In this article, the change in the size of the gamma prime (γ) with respect to high temperature exposure was characterized using scanning electron microscope and the Larson-Miller parameter (LMP) was measured.
16
Failure Analysis of an Aero Engine Ball Bearing
TL;DR: In this article, an aero engine failed due to the misalignment of the ball bearing fitted on the main shaft of the engine, which was later replaced by a new bearing.
15
Fatigue failure of a centrifugal compressor
TL;DR: In this article, a single stage centrifugal type compressor failed during operation and a blade detached from the root in an over load manner, and the detached blade collided with other rotating part of the engine and entangled between the compressor and multiplier assembly.
