Mössbauer spectroscopy analysis on a tempered martensitic 9% Cr steel
(Springer, 2009-11)
We report an analysis by means of Mössbauer spectroscopy, on a 9% Cr steel submitted to a tempering process at 780°C. Spectra of several samples with different tempering times obtained at room temperature are fitted, and ...
Petrographic characterization and identification of temper sources in local ceramics during the Inca domination and early Spanish colony (Mendoza, west-central Argentina)
(Elsevier, 2017-06)
This work relies on the potential use of petrography to determine temper provenance and applies it to ceramics of west-central Argentina. Petrography is used to identify the raw materials, production technologies and, for ...
Moisture migration during a tempering time after the heat treatment step in yerba maté processing
(Planta Piloto de Ingeniería Química, 2011-04)
The aim of this research was to study the effect of applying a tempering time to the branches of yerba maté after the heat treatment stage (or sapecado). Assays were carried out in three industrial producers of Misiones ...
First record on an amphibian in the canopy of temperate rainforests of southern South America: Eupsophus calcaratus (Cycloramphidae)
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2010)
Levantamento da cinética de revenimento de um aço-carbono ligado ao V, B, Cr, Ni e Mo
(Universidade Federal de Minas GeraisUFMG, 2010-07-01)
The effects of temperature and time on the kinetics of tempering has been evaluated by hardness, tensile and Charpy V-notch tests of specimens quenched and tempered in the range 580 to 680°C. Johnson, Mehl and Avramis ...
A two-step estimation procedure for locally stationary ARMA processes with tempered stable innovations
(2023-03)
The class of locally stationary processes assumes a time-varying (tv) spectral representation and finite second moment. Different areas have observed phenomena with heavy tail distributions or infinite variance. Using ...
Effect of two drying processes about soybean seed quality
(Chinese Academy of Agricultural Mechanization Sciences, 2017-12)
This work studies the effects of two drying processes on quality soybean seed. This study compares simultaneouslythe effects of two drying processes: the dry-aeration process and conventional drying process. Two drying ...
Influence of phosphorus content and quenching/tempering temperatures on fracture toughness and fatigue life of SAE 5160 steel
(ABM, ABC, ABPol, 2010)
This study investigates the influence of quenching/tempering temperatures on the fracture toughness and fatigue life of SAE 5160 steel, considering different phosphorus contents. Quenching and tempering treatments were ...
