Simultaneously Improved Bendability and Strength of Al–Mg–Si–Cu–Zn Alloys by Controlling the Formation and Evolution of Primary Fe-Rich Phase

In present work, the formation, evolution, and distribution of the primary Fe-rich phase in an Al–Mg–Si–Cu–Zn–Fe–Mn alloy are coupling controlled by ultrasonic melt treatment (USMT) and thermomechanical processing (TMP). It is shown in the results that the size of grains and Fe-rich phase in the as-cast state can be greatly reduced by the...

Effect of the initial microstructure and thermal path on the final microstructure and bendability of a high strength ferrite-martensite dual phase steel

The combined effects of the initial microstructure and heating rate on ferrite recrystallization, austenite formation and transformation kinetics of a regular ferrite-martensite dual phase steel are investigated. Special attention is given to the effect of the martensite distribution on mechanical properties, particularly the bendability....

Design of a Compliant Escapement Mechanism

This thesis describes the design process for an iso-frequent oscillator. Instead of designing the perfect linear spring for a harmonic oscillator, non-linearities in the force deflection behavior of the spring are allowed. These inperfections are then compensated by propper transmission design.
