The characterization and optimization of the microstructures of materials pertaining to
material properties is a primitive necessity to ensure the performance and service life of the …

For investigating the effect of phases on sound velocity, thin disk shaped samples were
prepared from AISI 4140 and AISI 5140 steels. An initial heat treatment was applied to all …

The aim of this study is to compare the performance of magnetic Barkhausen noise and
ultrasonic methods for the evaluation of the microstructure of commercial steels. Following …

Precise measurements of shear wave velocities have been made in 20% cold worked and
annealed samples of alloy D9 (Ti-modified austenitic stainless steel) to characterize the …

In this study an attempt has been made to determine the influence of the deformation and
the thermal treatment given to a steel forging on the ultrasonic velocity and its attenuation …

The ultrasonic testing technique is widely used for obtaining information about the
microstructural and mechanical properties of metals in recent years. An advantage of using …

The aim of the study is to characterise hot-rolled and heat-treated plain-C steels (SAE 1020
and 1050) by ultrasonic velocity and attenuation measurements. Various heat treatment …

The aim of the study is to investigate the effect of quenching and tempering on sound
velocity of steels, and to contribute to the nondestructive control and optimisation of the …

The dynamic elastic properties of the thermal cycle simulated weld heat-affected zone (HAZ)
of SA 508 Class 3 RPV (reactor pressure vessel) steel were investigated by resonant …

The aim of this thesis is to investigate the effects of Mn content and alloying additions such
as Cr and Mo, and various heat treatment procedures on both microstructure and …
