On the role of Ag in enhanced age hardening kinetics of Mg–Gd–Ag–Zr alloys

The addition of Ag to the age hardenable Mg–Gd–Zr alloy system dramatically enhances early stage age hardening kinetics. Using atom probe tomography (APT), Ag-rich clusters were detected in a Ag-containing Mg–Gd–Zr alloy immediately after solution treatment and water quenching. During subsequent isothermal ageing at 200 °C, a high density of basal precipitates was observed during the early stages of ageing. These basal precipitates were enriched with Ag and Gd, as confirmed by APT. It is posited that Ag-rich clusters in the context of quenched-in vacancies can attract Gd atoms, increasing diffusion kinetics to facilitate the formation of the Ag + Gd-rich basal precipitates. The rapid formation of Ag + Gd-rich precipitates was responsible for accelerated ageing.     

Supervisor Support and Organizational Commitment: The Role of Work–Family Conflict,Job Satisfaction,and Work–Life Balance

Building on conservation of resources theory and social exchange theory, the author examined the relationship between supervisor support and organizational commitment through work–family conflict, work–life balance, and the job satisfaction of employees working in the financial sector in Australia. The study comprised 305 employees recruited through an online survey. Results indicate that supervisor support is negatively related to work–family conflict. In turn, work–life balance and job satisfaction are negatively linked to work–family conflict. The results further show that both work–life balance and job satisfaction are positively related to organizational commitment. Theoretical and practical implications, as well as limitations, are discussed.

Supervisor Support for Employee Performance in Australia: Mediating Role of Work‐Life Balance,Job, and Life Attitude

Drawing on the job‐demands resources model, we investigated the relationship between supervisor support and employee performance and the mediating effects of work‐life balance (WLB), job and life satisfaction, and organizational commitment in a sample of 305 financial‐sector employees in Sydney, Australia. Results reveal that supervisor support is positively related to employee performance, WLB, job and life satisfaction, and organizational commitment. In turn, WLB, job and life satisfaction, and organizational commitment are positively linked to employee performance. The findings indicate a significant mediation between supervisor support and employee performance only through WLB and organizational commitment. Implications for theory and practice are discussed.
