It easier than you think to repair your book. Using a book or binding glue can help you reattach pages that have come loose from the book. Hot tearing is a common and severe defect in casting and it is perhaps the pivotal issue defining an alloy's castability. The subject has been extensively studied through various perspectives for Author: Geoffrey Sigworth.
Book Chapter Castability—Fluidity and Hot Tearing By Lars Arnberg Lars Arnberg Norwegian University of Science and Technology Various tests designed for measuring the hot tearing tendency in alloys are discussed. The article also discusses the temperature dependence, criteria, and modeling of hot tearing.
from book Essential Readings in Light Metals: Hot tearing susceptibility was quantified in two ways. The first method involved measuring the load at the solidus temperature (°C).

In the past, there has been some Cited by: 3. Jun 30, · Hot tearing during solidification of aluminium alloys castings can be a serious problem. This phenomenon is well known but still insufficiently investigated.
Hot tearing occurs in form of irregular cracks in metal castings that develop during solidification and cooling. The cause of hot tearing is generally attributed to the development of thermally induced tensile stresses and strains in a Author: Marek Brůna.
Mg-Zn alloys are widely used as wrought alloys such as ZM, ZK and ZE series. They are reportedly to be prone to hot tearing due to the presence of Zn.
The present work first evaluates the hot tearing susceptibility (HTS) of binary Mg-Zn alloys using quantitative experimental methods and thermodynamic simulations based on Clyne's model, and then further investigate the addition of aluminum on Cited by: Both cover and pages are stuck together at the spine edge by a thick layer of hot melt glue.
