Production of copper-based shape memory alloy using powder metallurgy methods

A Cu-based shape memory alloy is produced using PM methods. The Cu-16.5Zn-6.5Al alloy is prepared from elemental powders. The production route includes the various combination of sintering, hot pressing and hot rolling. Zinc loss due to evaporation could not be avoided in conventional compaction and sintering route. On the other hand, a homogenization treatment after hot pressing leads to formation of pores in the microstructure. Directly hot rolled specimens after a hot pressing operation showed shape memory effect, which is most probably due to that zinc loss is minimized.

Production and characterization of porous titanium alloys
Esen, Ziya; Bor, Şakir; Department of Metallurgical and Materials Engineering (2007)
In the present study, production of titanium and Ti6Al4V alloy foams has been investigated using powder metallurgical “space holder technique” in which magnesium powder were utilized to generate porosities in the range 30 to 90 vol. %. Also, sintering of titanium and Ti-6Al-4V alloy powders in loose and compacted condition at various temperatures (850-1250oC) and compaction pressures (120-1125 MPa), respectively, were investigated to elucidate the structure and mechanical properties of the porous cell walls...
Characterization of Ti-6Al-4V alloy foams synthesized by space holder technique
ESEN, ZİYA; Bor, Sakir (2011-03-25)
Ti-6Al-4V foams, biomedical candidate materials, were synthesized by powder metallurgical space holder technique as a result of evaporation of magnesium to achieve desired porosity content. Final products contained porosities in the range similar to 43-64% with an average macropore size between 485 and 572 mu m and a lamellar type Widmanstatten microstructure composed of alpha-platelets and beta-laths. Unlike the case of bulk Ti-6Al-4V alloy tested under compression loading, compression stress-strain curves...
Characterization of dual phase steels by using magnetic barkhausen noise analysis
Kaplan, Mücahit; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2006)
The aim of this work is to nondestructively characterize the industrial dual phase (ferritic-martensitic) steels (DPS) by the Magnetic Barkhausen Noise (MBN) method. By quenching of AISI 8620 steel specimens having two different starting microstructures, from various intercritical annealing temperatures (ICAT) in the ferrite-austenite region, the microstructures consisting of different volume fractions of martensite and morphology have been obtained. The microstructures, strength properties and hardness val...
Characterization of steel microstructures by magnetic barekhausen noise technique
Davut, Kemal; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2006)
This aim of this thesis is to examine the possibility of using Magnetic Barkhausen Noise (MBN) technique in characterizing the microstructures of quenched and tempered low alloy steels as well as annealed low carbon steels. To determine the average grain size by MBN, SAE 1010 steel consisting of dominantly ferrite was used. The specimens were slowly cooled in the furnace after austenitizing at different time and temperature variations. By metallographic examination the average ferrite grain size of specimen...
DÖNMEZ, Arif; Evis, Zafer; Department of Engineering Sciences (2022-8-22)
This thesis focuses on the characterization of simple, face-centered and diamond cubic lattices produced by fused deposition modeling (FDM) using polylactic acid (PLA) under uniaxial compression loading condition. Four design parameters were set for each cubic lattice: with radius, without radius, hollow truss, and hollow and with radius. Test items were manufactured for all designed structures. Since changing the manufacturing direction changes the mechanical properties of cubic lattices, the tests were do...
