Stirnol Engine: A combination of Nitinol (shape memory alloy) and Gamma Stirling Engine

Studies of selected mechanical properties of nitinol – shape memory alloy

Because of their specific properties, shape memory alloys are applied in many domains. The investigations were conducted on nitinol alloy in the form of 3,1 mm diameter wire, whose Af temperature as stated by the manufacturer is Af =65C. The wire was stretched in a strain hardened state and after annealing at 500C. The influence of different heat treatments on the engineering stress – strain cu...

Fabrication of Spiral Stent with Superelastic/ Shape Memory Nitinol Alloy for Femoral Vessel

Stent is a metal mesh tube for opening the obstructed vessels of the body. Ni-Ti alloy is a suitable metal for fabrication of stent due to its potential for applying the appropriate stress and strain to the vessel walls. In this study, super-elastic Nitinol wire was used to build stent samples usable to open femoral vessel. Ageing was performed at 500°C for different periods of time to determin...

Experimental investigation on the gamma model Stirling engine for cooling production using various gases

The Stirling Cycle is one of the thermodynamic cycles that is close to Carnot cycle in term of theory, and these advantages cause to using Stirling engines in wide industries. The main objective of this research is experimental investigation of Stirling Gamma engine for refrigeration. In this investigation, effect of working fluid air and helium, operatring pressure of working fluid and dynamo ...
