Vickers Hardness Test in Perspective

Vickers hardness test

Hardness testing is a precision science whose estimates are used in mechanical works. There are 4 different types of hardness testing, each with a different approach but with the same outcome. Vickers Hardness test is one of them. The system of hardness testing was designed as an alternative to the Brinell method. Whereas the Brinell process banked on ball size, test force, and sample dimension, the Vickers method derived its outcome from the ability of the indenter to penetrate the material.

How Vickers Testing Works

To get the measure of hardness of any material, the calculations are compared to how the material resists plastic deformation. What makes Vickers testing stand out is that it can be used on any material. Also, the size of the indenter does not influence the hardness of the material.

The pyramid-shaped indenter compresses the material to produce geometrical impressions. The impressions give the measurement points from which the hardness calculations derive. The Vickers hardness test is given as the Diamond Pyramid Number (DPH) or Vickers Pyramid Number (HV). The measurement scale is among the widest, which makes Vickers universal.

Reading from the Vickers test comes in xxHVyy/zz formula.

xx is the hardness number

yy is the mass of the test load while

yy is the time taken to load the mass.

HV is the material’s hardness.

The most popular Vickers Hardness test equipment is the Falcon series; 400, 450, 500, 600, and 5000.

Guidelines for Baseball Darts

The basic rule of baseball dart is similar to the actual game baseball. Players need to score more points in every inning to win the game baseball darts. The rule involves hitting the number that matches the current inning. For instance, you need to hit number 1 on the dartboard in the first inning. The game continues until 9 innings are over. 

Extra Innings

Usually, the game is played till 9th innings. However, if the match is in a tie till the end of 9 innings, the players can continue playing extra innings. In the 10th inning, 10 is the target, 11 is the target in 11th inning and so on. You can play until the winner is determined clearly. 

Scoring in the Game

To keep score in baseball darts, you need to pre-mark the nine rounds before starting innings. The names of the players should be mentioned at the top of the dartboard. When they play, the score is marked for every individual beside the spot allotted for every inning. Playing in a team will give you the chance to create a column for the running score. If you have space, you can keep the scoreboard horizontally like traditional baseball rule. 

Variations in Rule

A variation on the rule includes playing with a 7th inning stretch. It creates an additional rule of the game, which implies that a player being unable to score a run in the 7th inning, will get half of the entire score. Playing with this stretch often may break a game. 

Dummy Player

A baseball darts game can be played with teams. If the teams are uneven, you may need to include a dummy player. It will allow you to even out the scoring. A dummy can have a predetermined score depending on the level of skill of the players. The score is divided equally amongst the innings.

In these games, triples are king and 9 is the highest possible score per player in every inning, which contains three triples. A perfect baseball dart game needs a score of 81 points.
