    Temperature dependence and microwave enhancement of the critical current of superconducting microbridges (1973)
    Springer
    Journal of low temperature physics 13 (1973), S. 175-183 
    Details

    Topics: Physics
    Notes: Abstract The temperature dependence of superconducting tin, thin-film, narrow bridges has been investigated. NearT c the critical current varies with (1 − T/Tc α), with a distribution of α values between 1 and 3/2. It is suggested that the α values can be used to characterize the bridges. The microwave enhancement ofI c andT c was measured and these data were compared with a recent theory by Christiansenet al. on the microbridges. We found that their theory gives a correct prediction for the Dayem effect in the bulklike bridges (with α=3/2) while their theoretical values for the junction-like bridges (with α=1) are not in agreement with our data.

    Fatigue studies on dual-phase low carbon steel (1981)

    Notes: Abstract Low cycle fatigue studies have been carried out on 2 wt% Mn, 2 wt% Si and 0.1 wt% C steels with dual-phase and tempered martensitic structures. Fatigue crack initiation and propagation were investigated using scanning electron microscopy as well as optical microscopy. In addition, taper-section and cross-section techniques were also performed for more detail studies on the correlation of crack initiation with the internal microstructures of the testing samples. Internal microstructures were also investigated on the dual-phase steel sample before and after fatigue fracture by transmission electron microscopy.

    Stability and work hardening of an Fe-12Cr-23Mn austenitic steel (1985)

    Notes: Abstract The effect of pre-strain on the strain-induced martensitic transformation of an Fe-12Cr-23Mn austenitic steel has been investigated through transmission electron microscopy and X-ray analysis. Pre-strain was performed either at room temperature or at 200° C. Final strain was carried out at liquid-nitrogen temperature. Theε phase was shown to form on {1 1 1} planes of the austenite matrix predominantly by overlapping of stacking faults. The martensite transformation sequence wasγ →ε →α. Nucleation of theα phase mainly occurred at intersections ofε bands. Austenite stability was shown to increase by pre-strain at 25° C or 200° C. Pre-strain at 200° C has a greater effect on austenite stability than does pre-strain at 25° C. The mechanism was discussed in terms of martensite transformation rate and various substructures introduced during straining. Work hardening was shown to depend on the degree of pre-strain and final strain. The correlation between work hardening and substructures introduced during straining was examined.

    Effect of nitrogen and nickel on the stability of an Fe-12Cr-23Mn austenitic steel (1986)

    Notes: Abstract The effect of nitrogen and nickel on the austenite stability and the structural changes as a result of cold work of an Fe-12Cr-23Mn alloy steel has been examined by transmission electron microscopy and X-ray analysis. Prestrain was performed either at room temperature or at 200° C. Final strain was carried out at liquid nitrogen temperature. The volume fraction of strain-induced martensite decreased by 40% and 12% due to the addition of 2.43% Ni and 0.11% N, respectively, despite whether prestrain was performed or not. The mechanisms are discussed in terms of the ɛ phase, stacking faults, dislocation cells and dislocation tangles induced by prestrain and final strain.

    Tensile and fatigue properties of a thermomechanically treated 7475 aluminium alloy (1988)

    Notes: Abstract High-purity Al-Zn-Mg alloy was thermomechanically treated. The process included solution treatment, pre-ageing, cold-working by rolling and final ageing. Pre-ageing was carried out at 100°C (TAHA1) and room temperature (TAHA2). Experimental results indicated that the TAHA1 process improved the tensile strength significantly while the TAHA2 process improved the fatigue life more substantially. Fatigue crack initiation sites were examined carefully by scanning electron microscopy. A correlation between fatigue crack initiation, fatigue striation, tearing ridge, dimple distribution and fatigue life was observed. The experimental results are discussed in terms of substructure and are also compared with the tensile and fatigue properties of a thermomechanically treated 7075 Al-Zn-Mg alloy which were previously reported by one of the authors.

    The effects of pre-ageing on a thermomechanically treated 6201 aluminium alloy (1988)

    Notes: Abstract The effects of pre-ageing on the tensile properties of a thermomechanically treated 6201 aluminium alloy were examined. It was found that the pre-ageing effects can be either beneficial or detrimental depending on the amount of cold work applied prior to final ageing. The pre-ageing performed was at 135° C for 30 min. The final ageing was at 140° C for various time periods. Pre-ageing combined with 60% cold work improves the tensile properties. However, pre-ageing combined with 80% cold work shows a detrimental effect on the tensile properties of 6201 alloy. The mechanisms are explained in terms of transmission electron microscopy.
