Can you explain why Ti-C bonds would be stronger than Fe-C bonds?

The only reason I can see why Ti-C bonds might be longer than Fe-C bonds is that Ti atoms are larger than Fe atoms.
The decrease or increase in atomic size is one of the few diagonal trends that can be known by looking at the periodic table.
Starting with the bottom left of our periodic table, size decreases going up in a group or right in a period.
We see that Fe is the the right of Ti in the period so we can conclude that Ti is larger than Fe.
