Effects of TiC Content on the Microstructure and Mechanical Property of WC-TiC-TaC Cemented Carbides

Grinding effects on surface integrity and mechanical strength of WC-Co cemented carbides

In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface conditions: (1) ground, (2) mirror-like polished (reference), and (3) ground plus high-temperature annealed, are investigated. Surface integrity and mechanical characterization is...

The Effect of sintering temperature on microstructure and hardness of milled WC- 20 wt.% equiatomic (Fe,Co) cemented carbides

In this study, WC–20 wt.% equiatomic (Fe,Co) powder mixture was milled in a planetary ball mill. The effects of different milling time (15 min, 5h, 10h, and 25 h) and sintering temperatures on the microstructure and mechanical properties of this equi-Fe substituted cermet were investigated. The structural evolution and the crystallite size changes of the powders during milling were monitored by...

the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...

Augmented Reality Tic-Tac-Toe

This project implements an augmented reality version of Tic-Tac-Toe. In this game, the user draws an X on a paper board. Using a webcam and digital image processing techniques, the computer then determines the board state. Using this information, the computer chooses a move and displays the move in the appropriate place on the screen. Our finalized algorithm successfully completes these steps w...
