Assessment of Retained Austenite in AISI D2 Tool Steel Using Magnetic Hysteresis and Barkhausen Noise Parameters
Inaccurate heat treatment process could result in excessive amount of retained austenite, which degrades the mechanical properties, like strength, wear resistance, and hardness of cold work tool steel parts. Thus, to control ...
Electromagnetic nondestructive evaluation of tempering processin AISI D2 tool steel
The present paper investigates the potential of using eddy current technique as a reliable nondestructive
tool to detect microstructural changes during the different stages of tempering treatment in AISID2 ...
Applications of Impedance Plane and Magnetic Differential Permeability in Microstructural Characterization of AISI D2 Tool Steel
Two nondestructive electromagnetic techniques, hysteresis loop and eddy current methodologies, have
been used to characterize the microstructural changes of D2 tool steel in the course of quench and
tempering ...
بررسی اثر روش لایه نشانی دی اکسیذ تیتانیوم (TiO2) بر عملکرد سلول خورشیذی حساس شذه با رنگذانه (DSSC)
در این تحقیق اثر دو روش لایه نشانی دکتر بلید و لایه نشانی چرخشی بر عملکرد و بازده DSSC بررسی شد. نتایج نشان می دهد که در روش پوشش دهی چرخشی تخلخل و جذب رنگدانه کمتر است ولی بدلیل ایجاد پوشش با ترک کمتر بازده ان بیشتر است.
Microstructural Characterization of Quenched AISI D2 Tool Steel Using Magnetic/Electromagnetic Nondestructive Techniques
In the past decade, nondestructive electromagnetic techniques have been extensively used for the characterization of materials.
In this paper, the relation between the microstructural/mechanical characteristics of ...
Determination of martensite start temperature using an electromagnetic nondestructive technology
Assessment of martensite start temperature in alloy steels is of critical importance for many industrial
applications of hardenable steels. To determine this, dilatometry is often carried out by characterizing ...
Effect of sample initial magnetic field on the metal magnetic memory NDT result
One of the major concerns regarding the use of Metal Magnetic Memory (MMM) technique is the complexity of residual magnetization effect on output signals. The present study investigates the influence of residual magnetic ...
