Influence of different grades of CBN inserts on cutting force and surface roughness of AISI H13 die tool steel during ha...
Now-a-days, the application of hard tuning with CBN tool has been massively increased because the hard turning is a good alternative to grinding process. However, there are some issues that need to be addressed related to the CBN grades and their particular applications in the area of hard turning process. This experimental study investigated the e...
A Further Evaluation of the Coupling Relationship between Dephosphorization and Desulfurization Abilities or Potentials ...
The coupling relationships between dephosphorization and desulfurization abilities or potentials for CaO-FeO-Fe2O3-Al2O3-P2O5 slags over a large variation range of slag oxidization ability during the secondary refining process of molten steel have been proposed by the present authors as log L-P + 5 log L-S or log CPO43- + log CS2- in the reducing z...

Thermodynamic Evaluation of Reaction Abilities of Structural Units in Fe-O Binary Melts Based on the Atom-Molecule Coexi...
A thermodynamic model for calculating the mass action concentrations of structural units in Fe-O binary melts based on the atom-molecule coexistence theory, i.e., AMCT- model, has been developed and verified to be valid through comparing with the calculated activities of both O and Fe over a temperature range from 1833 K to 1973 K (1560 A degrees C...
Statistical justification of Model B4 for drying and autogenous shrinkage of concrete and comparisons to other models
The shrinkage prediction part of Model B4 presented in the preceding paper is here statistically justified by optimal fitting of the new NU database containing 1050 test curves and by statistical comparisons with the existing shrinkage prediction models. Rather than attempting a point-wise constitutive model for free shrinkage, Model B4 predicts th...
Comprehensive database for concrete creep and shrinkage : analysis and recommendations for testing and recording
The first large worldwide database of creep and shrinkage tests was assembled at Northwestern University (NU) in 1978. It was expanded as the RILEM database in 1992 and further in 2008. A major expansion, completely restructured and verified, named the NU Database, is now presented. The number of the test curves of creep and drying shrinkage is mor...

Statistical justification of model B4 for multi-decade concrete creep using laboratory and bridge databases and comparis...
This paper presents: (1) statistical justification and calibration of model B4 using laboratory creep data and long-term bridge deflection data, and (2) statistical comparisons of various types with the existing creep prediction models of engineering societies. The comparisons include the 1995 RILEM Recommendation (Model B3), fib Model Code 1999, M...
