Mechanical Properties and Microstructural Evolution of AA5083/Al2O3 Composites Fabricated by Warm Accumulative Roll Bonding [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2016 In this study, warm accumulative roll bonding (Warm- ARB) process has been used to produce Metal Matrix Composite (MMC: AA5083/-5% Al2O3). Starting materials were roll bonded as alternate layers up to 5 rolling cycles with 300°C preheating for five ...

MATERIALS TRANSACTIONS, 2003 The differential speed accumulative roll bonding (DSARB) process was attempted to strengthen 1100 aluminum sheet via grain refinement. The roll peripheral speed of one roll was 2.0 m/min and that of another roll was 3.6 m/min. The roll speed ratio was kept at 1.8. The accumulative roll bonding was conducted up to 6 cycles at ambient temperature without

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Nanograined Ti–Nb microalloy steel achieved by Accumulative Roll Bonding (ARB) process
Materials Science and Engineering: A, 2013 Abstract Over the last decade, nanocrystalline and ultra-fine grained (UFG) materials with grain size less than 1 μm have aroused considerable interest due to their superior mechanical properties compared to conventionally grained materials. In this work Ti–Nb microalloy steel was processed by the severe plastic deformation (SPD) technique called ...

ESG Performance and Credit Risk: Evidence From Chinese Manufacturing Companies
International Journal of Finance &Economics, EarlyView.ABSTRACT This study investigates the effect of corporate environmental, social, and governance (ESG) performance on credit risk using a sample of manufacturing firms listed on China's Shanghai and Shenzhen A‐share markets from 2009 to 2021. Employing fixed effects, the generalised method of moments, and instrumental variable models, we find that ...

Evolution of the microstructure, texture and creep properties of the 7075 aluminium alloy during hot accumulative roll bonding [PDF]
, 2014 The 7075 Al alloy was severely deformed at 350 °C by a 3:1 thickness reduction per pass accumulative roll bonding (ARB) process up to six passes. It was found that discontinuous recrystallisation occurs during the inter-pass annealing stages from the ...

Monetary Policy, Investor Sentiment and Stock Price Bubble: Evidence From China
Accounting &Finance, EarlyView.ABSTRACT The empirical results indicate that an increase in interest rates may stimulate a significant and persistent stock price bubble, which is consistent with rational asset price bubble theory. This finding suggests that central banks should implement anti‐turbulent monetary policy with caution, since inappropriate tightening may unintentionally ...
